Notch: "See, the problem with Minecraft for the Ouya is that it's android, and our android version of Minecraft isn't exactly that super great."
They've been working on it, but it still doesn't compare well to the PC version, or even the Xbox release. People are willing to accept a bit of a gimped version of their phone, because it's running on their phone. On a console (even one that costs less than a phone did) I think they'll have some trouble overcoming that.
It could happen, but a proper version of Minecraft for Ouya would take some effort. If they get enough adoption for Mojang to bother, that could be the tipping point that pushes it to popularity.
